Title: Improvements in or relating to two-state circuits

IPC: H01P1/15
Filed: 1960-02-08
Abstract: 977,141. Controlled non-linear capacitors; transmission systems. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Feb. 2, 1961 [Feb. 8, 1960; Nov. 18, 1960], Nos. 4350/60 and 39664/60. Headings H3B and H4R. A transmission line is divided into two branches each of which includes a biased diode functioning as a variable capacitor and a circuit for detecting the presence of an alternating signal in the branch, the detecting circuits and biased diodes being cross-connected so that A.C. transmission through any one branch prevents transmission through the other branch. As shown in the drawing accompanying the first Provisional Specification, a coaxial transmission line 1 has branches 3, 4 each shunted at one quarter of a wavelength from the junction by a circuit comprising an inductor 13, capacitor 14 and diode 7. Each diode is biased in the non-conductive sense by a potential- V, and this potential is increased when an alternating signal is detected in the other branch by a transformer 24. As a result the shunt circuit resonates and prevents transmission along the associated branch. Initially the branch which permits signal conduction is arbitary. To change over the conductive state, a signal is applied to an input 29 or 31 which increases the bias on the diode in the conductive branch and so terminates transmission. This removes the extra bias applied to the other branch diode by the associated detecting circuit and enables it to conduct. In the other figure (second Provisional Specification), a coaxial transmission line 40 has quarter wavelength #/4 branches 41, 42 of characteristic impedance Zo. These branches each terminate in 4-way coaxial joints 43, 44 which provide feeds to terminated line sections 45, 46 of impedance 2Z 0 , #/4 sections 49, 50 terminated by impedances Zr and of impedance Zs, sections 47, 48 of length between #/4 and #/2 ; including biased diodes 51, 52, and output lines 61, 62. The detecting circuits comprising capacitors 53, 56 and rectifiers 54, 57 are connected to the sections 49, 50, and when energized vary the bias voltage V applied to the diodes 51, 52 to change their capacitance. The stable state of the system may be changed by applying a potential to terminal 59 or 60 as the case may be.

Title: Improvements in dyeing apparatus
Inventor: LUCZYNSKI WLADYSLAW FILIP
IPC: D06B11/00
Filed: 1959-02-10
Abstract: Apparatus for the continuous dyeing of textile material comprises means for impregnating the material with a dye solution or suspension, an elongated, substantially vertical, chamber having an entrance and exit at its upper and lower ends respectively, means for heating the interior of the chamber and means for passing the impregnated material through the chamber in a downward direction.  As shown in Fig. 1, textile fabric 1 is passed over roller 59 into a trough 3 of dye solution, under roller 5 and thence between padding rollers 4, 50, positively driven by belt 51 from a drive pulley 35. The fabric then passes <FORM:0887735/IV (c)/1> <FORM:0887735/IV (c)/2> down the centre of a tube 6, surrounded by heating jackets 7, 8 thermostatically controlled by switches 38, 39.  At the lower end of the tube the fabric passes into a liquid 11, e.g. water, in a vessel 12, the arrangement being such that the tube is partly immersed in the liquid, thus sealing it off.  The fabric passes under guide rollers 13 immersed in liquid 11, over a driving roller 14, over and under guide rolls 15, 18 and thus through fluids 17, 19 in baths 16, 20.  The latter have heaters 37 mounted therebeneath.  If desired the fabric may be passed over further rollers and through additional after-treatment baths.  The fabric is then passed in front of a heating element 21, the latter being associated with shaft 52 driven by a motor 53 which swings the heating element to one side when the fabric ceases to move through the apparatus.  The fabric then passes over a roller 22 and is wound up on a spool 23 on shaft 44.  A motor 24 driving a pulley 26 through a belt 25 imparts movement to the fabric.  The same motor 24 imparts friction drive to a pulley 35 through a belt 34 driven by pulley 33.  The pulley 35 is mounted on the shaft 44 which has a core 45 keyed thereto and biased against the interior of the flange of the spool 23 by means of a coil spring 46 which is anchored at the end by means of a peg 47 extending through the shaft 44 (see Fig. 2).  In a modification (not shown), the coil spring is biased to a friction plate which is splined to the shift into contact with the flange of the spool.  The spool 23 is carried on the core rotatable about the shaft.  A wing nut is screwed on to the shaft to hold the flange against the friction plate.  In another modification (not shown) three chambers are provided with their longitudinal axes parallel and vertical. Textile fabric is caused to pass downwardly through the first and third chambers and upwardly through the second chamber, over and under rollers located at either end of the chambers and through impregnation baths located above the chambers.  Specification 784,394 is referred to.

Title: Liquid level gauge
IPC: G01F23/284
Filed: 1973-01-30
Abstract: 1448282 Measuring fluid level electrically WHESSOE Ltd 30 Jan 1974 [30 Jan 1973] 4606/73 Heading H4D The level of a free surface of a fluent material is determined by inserting a transmission line in the material and measuring the time difference between a signal applied to the line and the signal deflected within the line. The transmisssion line 10, Fig. 2 (not shown), comprising an outer tubular metal conductor 11 and an inner helically wound conductor 12 terminated at their lower ends by a characteristic impedance 13 is immersed in the fluid 20 either vertically as shown or at an angle, e.g. when the fluid is in a pile. A clock pulse generator of the detection circuitry 30 applies signals A, Fig. 4, to trigger a flip-flop to provide signals B which after amplification are fed down the transmission line 10. The pulses are partially reflected at the surface of the material 20 and return with opposite sign back up the line, waveform C representing the applied and reflected signals at the input to the line. A discriminator is connected to the input of the line to provide signals only corresponding to the reflected signals and these are fed to the RESET input of a bi-stable circuit, to the SET input of which is applied waveform B. Waveform D at the output of the bi-stable circuit has a mark period corresponding to the interval T-t 1  and if T is made equal to the go-and-return time of pulses reflected from the far end of a transmission line which extends to the bottom of the container or the lower boundary surface if material 20 is uncontained t 2  is a measure of the depth of fluent material 20 above its lower boundary surface whether or not the line extends throughout the full depth of the material. In order to obtain an indication of depth an analogue and/or digital meters 50, 51 is used and the output from the bi-stable is amplitude stabilized, filtered and fed to a scaling amplifier. If time period t 1  is measured a measure of the surface below a predetermined level of surface of the fluent material is obtained.

Title: Improvements in or connected with bomb sights for flying machines
IPC: F41G3/24
Filed: 1936-02-17
Abstract: 472,392. Bomb-dropping sights. LEIGH, W. Feb. 17, 1936, Nos. 4705/36 and 4576/37. [Class 92 (ii)] Relates to bomb - dropping sights of the kind in which automatic adjustments of the sight line are made to suit the changes in altitude and speed of the aircraft which may occur after the sight has been set. According to the invention, such automatic corrections are applied to the conventional type of sight comprising a horizontal frame 88, Figs. 1, 2, supporting a sliding fore sight x and a vertical frame 32 supporting a sliding back sight 33, the frame being supported for rotation with respect to a pillar 5. Further, to correct for the speed and direction of the wind, the frame as a whole is automatically tilted on horizontal trunnions 95, as the sighting device is rotated about a vertical axis, by the engagement of rollers 99 on the frame with a wind ring 100 which is set obliquely to suit wind speed. In the form shown, the back sight is adjusted vertically by an amount which varies inversely as the aircraft speed, and the fore sight is adjusted horizontally inversely as the square root of the height. The back sight adjustment is effected by an air speed motor 9, Fig. 1, driving a governor 18, the sleeve 22 of which rotates a cam 25 connected by a spring-controlled cable 30 with the sight 33. The fore sight x is similarly adjusted from an altimeter 8, Fig. 2, which drives a cam over which passes a cable leading to a second cam forming part of a differential gear in a box 78, the periphery of which leads by a cable 79 to the fore sight. The differential gear enables adjustments for bomb characteristics to be effected by a knob 81. The means for adjusting the wind ring 100 is shown in Fig. 4 as carried by a wind tube 103 which is connected by a disengageable clutch 106 with a compass tube 111, both tubes being rotatable separately or together within the pillar 5. The tube 111 is rotated by a telecompass y. By releasing the clutch 106 by lever 110 and rotating the knob 104, an index 105 is moved to suit the direction of the wind over a compass card on the upper part of the knob 124. This knob is then rotated to bring a wind speed scale opposite the index 105, such rotation inclining the wind ring 100 through links 130, 131. When the clutch 106 is re-engaged, the sight is under the control of the telecompass.

Abstract: 1,037,592. Automatic sales machines. SCHEIDT & BACHMANN G.m.b.H. Feb. 3, 1965 [May 30, 1964], No. 4717/65. Heading G4V. A credit totalizer in a vending machine comprises a wheel having two oppositely directed sawtooth systems at its periphery, the wheel being stepped in one direction by rotation of a knob using an inserted coin as a coupling, and being stepped in the opposite direction by a pawl driven by a shaft of a price calculator. Fig. 2 shows part of a liquid fuel dispenser, wherein an inserted coin, after testing, falls into one of slots 21a . . . 21d in a drum, so that rotation of a segment 22 by a manual knob through a one-way drive rotates drum 21 and cam 24 through 90 degrees, to operate levers 25 and 27 and pawl 28 once, and advance the wheel five teeth. If four coins are inserted, a pin on wheel 29 disables the coin tester, so that further coins are rejected. A button may be pressed so that a receipt is issued when the knob is rotated. When the fuel nozzle is removed from its holder, the pump motor is energized, and a slider 45 moved to disengage pawl 28, and engage pawl 49. Also the coin tester is disabled, if three or less coins have beon inserted. Rotation of shaft 52 by the fuel delivery meter reciprocates pawl 49, eccentrically mounted on gear 54, to step wheel 29 back. A pin on the wheel opens a fuel supply valve when a coin is inserted and closes it on return of the pin to the datum position and de-energizes the motor, with the usual throttling of supply towards the end. If coins of different value are to be accepted, the coin apparatus, including the knob, is repeated for each denomination, and each steps wheel 29 by an appropriate number of teeth. The apparatus may be locked to prevent automatic operation, a panel which normally displays the credit established then showing an appropriate legend.
